PIPE-VIASE'.

SPECIFICATION formingpart Of Letters Patent NO. 732,759, dated July 7, 1903.

Application filed October 17, 1902. Serial No. 127,624. (No model.)

To a whom it may concern:

Be it known that I, JOHN R. LONG, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Pipe-Vises; and I do declare that the following is a full, clear, and exact description of the invention,whicl1 will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to pipe-Vises; and the invention consists in an improvement in the style of pipe .vises disclosed and claimed, broadly, in my application for Letters Patent of the United States bearing Serial No. 127,623. In the said application I show a simple form of my new vise with provision for only a single form of adjustment, while in the present application I provide for two adjustments at right angles to each other, all

substantially as shown and described,and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal central sectional elevation of the vise on line A A, Fig. 2; and Fig. 2 is a plan view with a portion sectioned at the left. Fig. 3 is a cross-section on line W'W, Fig. 1.

As thus shown, A represents a bracket hav-' or to other work in progress and where it is necessary to have a vise on the ground to do the work properly and speedily, and hence also is the vise made as light in weight as is consistent with the work to be done. Now in such uses, as well as where avise is permanently located, it is often desirable that the vise be provided with what constitutes in a sense a universal adjustment rather than a single adj ustment, as in my other case above noted, and hence the bracket A has stud or trunnion or, upon which the secondary adjustment of the vise is eifected, while the primary adjustment is between the base comes between them.

proper,B,and the jaw orjaw member O. In

' this instance, however, base B is an intermediate part having a tubular sleeve 1), by which it is engaged upon trunnion a, and at right angles to this sleeve is the tubular bearing 2 for jaw G. A peculiarity of this base is its practically split or divided construction as far down as through the top of sleeve 17; but

it is integral at the bottom of said sleeve, and thisdivides the tubular bearing 2 into halves,

which are shown in this instance as spaced apart, but may be close together. However, some spacebetween them is necessary, as

rotation when clamping of the partsoccurs, as will hereinafter more fully appear. Then, again, I can spare metal at this point for lightness. j

' Thejaw or jaw member 0 has a hollow cylindrical barrel-shaped body3 projected into the bearing 2 of the base from what is regarded as the front of the vise, and a shoulder tresting against said bearing to limit its movement to the rear. It is also provided with a solid head 5 and-an opening 6 in the neck of said head for chain D, connected through this opening with screw E. The other end of chain D is detachably or adjustably engaged with a set of lugs 7on the head of the jaw and constructed to be engaged on ends of crosspins d, which connect the double links of chain D. Those lugs are spaced apart to let the chain lie between them and have inclined inner slots 9, as well as rear I walls adapted to be engaged by pins (1, so that there is a double, and hence a strong engagement, of the chain on said lugs.

The jaw member 0 is preferably cast and also is provided with a set of jaw-plates 10, set into shouldered recesses on opposite sides of head 5 and bolted or screwed thereto. The engaging edges of said plates extend outward beyond head 5 and are substantially V-' shaped, with serrated edges 12, so as to take a firm grip upon pipe P, while chain D is arranged to cooperate with these jaws and After bringing the chain around the pipe the slack is taken up as fully as possible,when the chain is engaged on lugs 7, and then the gripping of the pipe is effected by or through screw E.

G represents a cap or end piece which is the equivalent of a cap, resting against the rear end of tubular bearing 2 and loosely secured by screws 14 to the end of the jaw barrel or body 3. This allows both jaw and cap to be clamped against the ends of said bearing, at the same time to prevent rotation of the jaw when clamping has been effected. Now it will be seen that the screw does not itself turn when it is tightened,but it is free to slide in cap G and is operated by a preferably sleeve-shaped nut 11 on said screw and having its bearing against said cap and provided with a suitable handle J. With this construction the jaw D may be freely rotated about its axis in base B, while said base may be as freely rotated on bracket A and its trunnion a; but when the screw is tightened by turning nut H and the divided bearing 2 is clamped between cap G and shoulders 4 not only is the jaw member clamped or held from axial rotation, but the split base A is clamped on trunnion a and rotation thereon is for the time prevented. Thus the clamping mechanism, which first of all engages the pipe and holds it securely, works also to lock the vise on both its otherwise loose bearings. Necessarily the base B has at least enough spring in its make-up to rest loosely on its support A normally and to come together and lock on said support when clamping of the parts occurs.

It will be particularly noticed herein that the jaw member has no rectilinear movement at all, but only an axial rotary movement, and that the end surrenders are in cap H.

What I claim is-- 1. A pipe-vise consisting of a suitable support, a divided base rotatable thereon and provided with a tubular bearing in its top, a jaw axially adjustable in said base and mechanism adapted tolock said base and said jaw in the same operation, substantially as described.

2. A vise-support having a trunnion, a divided base rotatablysupported on said trunnion, a jaw axially rotatable in said base and held against length wise movement, and mechanism adapted tolock the jaw and the base at the same time against movement, substantiallyas described.

3. A suitable support and'a base having a divided upper portion and rotatably seated on said base at its lower portion, in combination with a jaw axially rotatable in the upper portion of the base and provided with a shoulder engaged against the base to prevent end- Wise movement therein, and means to look allsaid parts rigidly together in the same operation, comprising clamping mechanism ongaging the upper portion of the base and constructed to lock the jaw and the base against rotation, substantially as described.

4. The vise-support and the base rotatable thereon and divided transversely in two separate parts in its upper portion, thereby affordin g room to draw said portions toward each other and lock the base on its support, in combination with a jaw in said base having a shoulder bearing against the front thereof to prevent endwise movement, a cap fixed to the rear end of said jaw and bearing against the rear side of said base, and a screw, nut and chain to look all said parts rigidly together, substantially as described.

5. The support having a trunnion, the base having a sleeve fitting on said trunnion and divided transversely from its top down through said sleeve to'the trunnion and integralin its lower portion, the vise-jaw supported in the upperportion of the base and means connected with said jaw adapted to bear againstt-he sides of the base and clamp it tight upon its support, substantially as shown.

6. In pipe-Vises, a base and a support therefor on which the base is rotatable, said base being divided transversely down to said support, in combination with a jaw in said base, a locking-screw and a chain engaged therewith and with the said jaw, a cap secured to the outer end of the jaw and supporting said screw and a nut in the screw bearingagainst said cap, said jaw being held against endwise movementin the base, whereby when said nut is tightened the said parts are rigidly bound together, substantially as shown.

iVitness my hand to the foregoing specification this Gth day of October, 1902.

JOHN R. LONG.
